Patented Juiyafi, 1914.

To'alZ whom it may concern Be .it known that L'ALvIN J. BAssE'rT, a

l Milwaukee and .State ofl Wisconsin, have invented cert-ain new and useful Improvements in Gras-Fill ters; and I do hereby declare that the following is a full, clear, and exact description My invention lhas for itsobject to provide a simple, effective and economical gas filter and it consists in certain peculiarities of conv struction and combination of parts as set forth hereinafterwitlr reference to the accompanying ldrawings and subsequently In the drawings Figurel represents a cen- 4indicated by ine 1`1 of Fig.l 3; Fig. 2, a

Fig. v2%, and ig.l 3, a sectional plan view of said iilter, with parts brokenk away, the section being indicated byline 3- 3 of F 1.

Referring by characters to ,the drawings,v 1 represents a housing of' the drum type, divided into up er and lower compartments, 2, 3, respective y, by af centrally apertured partition-disk 4 having V-shaped intake and delivery ports 4', 4", therein. The housing is closed at its top and bottom by caps 5, 6,' respectively, having centrally disposed stuffing boxes 5'., The walls of the lower compartment 3 are provided lwith oppositely disposed gas intake and discharge ports 7 and 8 respectively, for attachment to suitable supply and delivery ,pipe mains, not shown. A valve-disk 9 isseated upon the partitiondisk 4 within the upperor filter compartment, the lsaid valve-disk being' provided with oppositely disposed xV-shaped ports 9', arranged to register 'with' the partition-disk ports, whereby the flow `of gas through the up er compartment is` controlled. This valli'e-disk has secured thereto a valve-stem .10 that is journaled in the partition-disk a ertures and also the lower capstujrgfboxi 6 through which stuiiing-box itextends, terminating with la squared -key-head 10 shown in Fig. 1, when the valve-disk ports, 9 are in register with their companion par#y tition-disk ports 4', 4, the lower housing such manner as to cut oif communication between the intake and discharge ports 7 and 8, this gate lbeing secured to the valve-stem.

The valve-disk 9 is centrally recessed for the reception of a trunnion 12 that forms part of a rectangular iilter frame v13 and theA upper lstretch of the same alsov carries a trunnion stud 2', which trunnion stud eX- f tends through e cap stuiiing-box 5', terminating with a key-head 12' Theva'rious stretches of the filter frame are L shaped inc'ross-section and thevertical webs thereof have fitted thereto a metallic screen sheet 15 preferably constructed from a perforated plate. A second screen sheet 15' contines a layer 'of lt'er material 16 that is interposed lbetween the sheets, which lterfmaterlal is preferably composed of glass-woo l, as this substance has been found to'4 produce the most efficient results.

The filter plates or screens have fitted' thereto a rectangular follower frame 1 7, and `the entire assemblage is confined by a series of bolts 17. Hence it will he seen that a fiat filter is produced which canreadily be dis- .mantledl for cleaning' and repairs, or' renewal as the conditions may require.

The transverse stretches ofthe iilter frame are arranged to have close fit relative to the inner face of the housing cap 2 and the corresponding face of the valve-disk 9, while` the longitudinal stretches of said frame4 eifecta practically closed joint relative to` I longitudinal ribs, which ribs project in,- wardly from the walls of the upperfhousing compartment at a right angle to intake and vdischarge ports ofthe lower compartment.

In the operation, ythis filter, as shown, is

alined with the ribs `and thus divides the upper or filter compartment in halves and the valve belng turned to register the ports, gas

under pressure will travel as indicated from l nipulated, whereby 'bh/@gate is swung opg to establish direct communication between compartment 3 is sub-divided by gate 11,.'in

the yintake and discharge ports 7 and-'8' and 2 5 mounted within the other housing compartis avoided, it being understood that, as the gas passes throu hthe outgoing screen, it tends to clear o'r low out the choked screen apertures of that sheet which had previously- 'acted as a receiving screen.

ing a ported partition disk therein dividing the housing intocompartments one of which has a gas intakev and a gas discharge port, a lstem projecting from the partition `disk through the ported compartment of the housing, a gate carried by the stem for regulating lcommunieation between the intake and discharge' ports, an' oscillatory frame ment, a 'iiatJilter carried by Lthe frame, and means'for reversing the position of said filter frame. f l

Y 2. A gas filter comprising a drum-like housing having a gas intake and a gas discharge port adjacent to one end and' arranged opposite each other, a centrally .apertured and ported partition-disk carried by the'housing whereby the same-is divided into a gas receiving' and discharge compart-l ment and a' filter compartment, a ported' disk-valve revolublyv mounted upon the parf Witnessesf i partment i arranged'to form close contact vwith the 'walls of said compartmentand valve-disk, and a ilat'ilter carried by `the frame.
